Angiosperms vs Gymnosperms Flashcards | Quizlet Corn provides food for humans and domesticated animals, and its derivatives (e.g., cornstarch and corn oil) are used in making cosmetics, adhesives, varnishes, paints, soaps, and linoleum. Many scientists believe that the progression from spores to seeds represents the evolution of the gametophyte staying with the parent plant instead of growing on its own. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers. Seeds also built in a higher resistance to drought, allowing germination when conditions were optimal. Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or naked seeds on the surface of scales or leaves. Apples (Malus) and pears (Pyrus) are important pome fruits of the family Rosaceae. Gymnosperms are "simpler" anatomically because they do not bear flowers or fruit, and although of different species, are usually only tall evergreens with brown cones. But the difference lies in presence or absence of covered seeds. The use of herbs and spices in cooking predates recorded history.
